doing that in your head is near impossible for an average human. also pretty hard to do on paper too.

uh not very difficult at all if you know the taylor series for arcsine doodthing;

though, it doesn't make much sense to use inverse trig functions on an angle doodthing;

I'm in "advanced" math classes, just one level below the absolute highest I could possible get into (and only like 25 people get into that per year and there's like 500 people per grade), and not a single teacher has ever talked about it.

Yeah my teacher just taught us for fun, he didn't need to.  powerofone; He also made us do sudoku before anyone had heard of it.
I <3 Mr Barret, I lived across the street from him when I was little.  powerofone;
I also love my 8th grade homeroom/social studies teacher, Mr Jacobs.

my teacher taught us combinatorics instead of trigonometry at the end of 8th grade baddood;

i didn't pay attention, though
